The hydrogen generator is equipped with its own microprocessor, with which you can control the operating modes of the device. It is microprocessor control that determines the autonomy of the device. Moreover, this allows you to control the basic and technical parameters of the device (pressure, flow rate, level of water poured into the tank, tightness of gas lines, electrolyzer current). For the manufacture of gas lines, exclusively inert materials are used. Technical specifications:

The device is equipped with a four-button keyboard, which is used to set parameters and control. The generator can operate in continuous mode for a long time. For refueling, especially pure or double-distilled water is used, and refueling can be done without turning off the device, on the go. Their advantage is that they significantly reduce, or even completely eliminate, the use of bottled gases to power chromatographs and gas analyzers. For nutrition, mainly double-distilled water is used, the quality of which must be no lower than grade B water according to OST 11.029.003–80, and the electrical resistivity must be no less than 1 Mohm x cm.

The devices operate from a single-phase AC electrical network with voltage from 187 to 242 W, frequency (50±1) Hz. Maximum safety of devices is achieved due to the absence of such a supply of substance in them, which could fill a chromatograph or laboratory in a short period of time. The performance of the device eliminates the occurrence of explosive situations, so the generator is considered safe to use.
